INTRODUCTION: For intra-articular distal radius fractures (AO Classification, type B2) with a displaced dorsal fragment, there remains much discussion on the fixation method for the dorsal fragment. To reduce the displaced dorsal fragment, we developed a new technique consisting of fenestration of the volar bone cortex, reduction using an intramedullary procedure, and fixation using a volar plate. This avoids necessity of dorsal approach. TECHNICAL NOTE: We performed this surgical technique in 2 patients and achieved a good reduced position without much injury to the bone cortex at the site of volar plate placement...

BACKGROUND: Intratendinous injections may have important effects on the properties of collagen microarchitecture, morphology, and subsequent mechanical properties of the injected tendon. The purpose of this study was to examine the effects of intratendinous PRP injections; the injectant retention within tendons, the distribution of intratendinous injectant, and whether intratendinous injection or needle fenestration alters tendon morphology or mechanics. METHODS: HASH(0x38dd750) DESIGN: Controlled Laboratory Study...

Chronic muscle & tendon injuries are one of the problems which are encountered by human being since last long time. These injuries are generally repetitive strain injuries, commonly found in athletes. There are various treatments which include conservative methods in initial stages to surgery in later stages. On minimal invasive aspect Ultrasound-guided fenestration and tenotomy surgery has been used with good results as an effective treatment of chronic tendinopathies.(1,2) There are various injectable agents which were also researched including simple solutions such as hyperosmolar dextrose(3) (prolotherapy) to complex orthobiologic agents such as bone morphogenic protein,(4) but none have achieved uniform success...

OBJECTIVE: To validate the feasibility and effectiveness of applying fenestrated stent grafts in canine aortic arches. METHODS: According to the anatomic characteristics of the aortic arches from four adult beagle dogs, a straight-type aortic coated vascular stent system from Lifetech Scientific (Shenzhen) Co., Ltd. was released in vitro, after which a square window was burnt out at the back tendon of the coated vascular stent with an electrocautery pen, and the fenestrated stent grafts were then returned in the catheter and delivery sheath, following the original release path...

INTRODUCTION: Lateral epicondylitis, commonly known as tennis elbow, is the most common cause of lateral elbow pain and the second most frequently diagnosed musculoskeletal disorder in the neck and upper limb in a primary care setting. Many therapeutic options, including conservative, surgical, and minimally invasive procedures, have been advocated for the treatment of lateral epicondylitis. Although numerous small studies have been performed to assess the efficacy of various treatments, there are conflicting results with no clear consensus on the optimal treatment...

OBJECTIVES: Restoration of extension in the metacarpophalangeal joints of the fingers as well as in the interphalangeal joint of the thumb by transfer of the superficial flexor tendons of the long and ring fingers (flexor digitorum superficialis III and IV). INDICATIONS: The indications for surgery are substantial loss and palsy of muscles innervated by the radial nerve and its roots. CONTRAINDICATIONS: The procedure is contraindicated by reversible radial palsy, palsy or substantial loss of flexors, limited passive mobility due to contracture, ankylosis or instability of the affected joints, instability of the wrist joint, palsy of the wrist flexors, ankylosis of the wrist joint in an unfavorable position, adhesions of flexor or extensor tendons, insufficient soft tissue coverage or soft tissue defects and passage of transposed tendons through scarred tissue...

INTRODUCTION: Traumatic telecanthus resulting from injuries to the naso-orbito-ethmoidal (NOE) complex is a difficult deformity to treat and involves both esthetic and functional aspects. Delayed or inadequate primary treatment often results in scarring and secondary deformities that are severe and make them extremely problematic to correct. The intricate anatomy of this area makes NOE injuries one of the most challenging areas of facial reconstruction. Several techniques were described to reconstruct the medial canthal tendon (MCT) and repair the telecanthus deformity...

Tendinopathy is a broad concept that describes any painful condition that occurs in or around a tendon.The ideal treatment for tendinopathy is still nebulous. Dry needling is a treatment method in which a special needle is placed into the focus of tendinosis. The aim of this procedure is to form fenestrations which may initiateadvantageous bleeding and thus bring about the influx of growth factors (activating healing and regeneration). Relevant clinical studies have often combineddry needling with autologous blood injection therapy...

OBJECTIVES: The purpose of this study was to determine whether any sonographic features of jumper's knee can predict the outcome after sonographically guided percutaneous patellar tendon fenestration. METHODS: Patients were identified between July 2001 and March 2009 who had clinical and sonographic findings of jumper's knee, who had failed conservative treatment, and who had sonographically guided percutaneous fenestration of the patellar tendon. Pain levels were assessed before and 4 weeks after fenestration...

BACKGROUND: The purpose of this study was to investigate the clinical efficacy of extended resection with osteotomy, fenestration and conservation of muscle (tendon) insertion in the treatment of bone tumors. METHODS: A total of 15 patients with locally aggressive bone tumors (Enneking stage II) in the adjacent muscle (tendon) insertion of the proximal extremity were enrolled in the present study (mean age of 29 years). Extended curettage of lesions with osteotomy, fenestration and/or conservation of muscle (tendon) insertion and internal fixation with a bone graft or bone cement was performed at stage I...

A potential treatment for chronic tendinosis or tendinopathy is percutaneous ultrasound-guided tendon fenestration, also termed dry needling or tenotomy. This procedure involves gently passing a needle through the abnormal tendon multiple times to change a chronic degenerative process into an acute condition that is more likely to heal. This article reviews the literature on tendon fenestration and describes the technical aspects of this procedure including postprocedural considerations. Although peer-reviewed literature on this topic is limited, studies to date have shown that ultrasound-guided tendon fenestration can improve patient symptoms...

PURPOSE: The authors designed a malleable awl using a Steinmann pin for transnasal medial canthopexy. METHODS: A Steinmann pin with a small eye at the end (00-0187-001-69, Zimmer Inc., Warsaw, IN, U.S.A.) was prepared, and its distal part was bent using pliers (01-9726, Walter Lorenz Surgical Inc., Jacksonville, FL, U.S.A.) to make it a semicircle with the diameter of the circle being the intercanthal distance of the patient. RESULTS: Transnasal medial canthopexy was performed for 5 patients with telecanthus...

OBJECTIVE: Chronic refractory common extensor tendinosis of the lateral elbow has been shown to respond to sonographically guided percutaneous needle tenotomy (PNT) followed by corticosteroid injection. In this analysis, we attempted to determine whether the corticosteroid is a necessary component of the procedure. METHODS: We performed PNT on 57 consecutive patients (age range, 34-61 years) with persistent pain and disability resulting from common extensor tendinosis...
